My invention relates to mechanism for handling heavy objects and'one of the purposes of the invention is the provision of' a -machine which practically eliminates the danger associated with the handling and storage of these objects.

Another urpose of the invention is the provision o? a laborsaving machine of the character described which enables one man to handle ob'ects which heretofore required the combine efforts of several men in their handling.

Another purpose of the invention-is the provision of a machine of the character described by-which'the operator iscarried on the grappling means adjacent the object being handled. v

My invention possesses other objects and valuable features, some of which will be set vention which is illustrated in the drawings forming part of the specification. It is to be understood that I do not limit vmyself to the showing made by the said,v description and drawings, as I may adopt varying forms of my invention within the vscope 'of the claims.

Referring to the drawings.: Figure 1 is a vertical sectional lview thru the carriage of my apparatus, the grappling means being vshowny pendantly supported therefrom in side elevation. The carriage trackway and a pile of paper rolls which the apparatus is especially adapted to handle are also shown in elevation.

Figure 2 .is a front elevation of my 'grapling means,'portions ofl .which are shown broken away to reveal the adjustment vand control mechanisms.

Figure 3 is a sectional view'of the grapcated by the line 3-3 of Figure 2.

. In broadly descriptive terms, theapparatus v forth in the following description of my in pling means, the plane of sectionbeing indiin handling objectsl exemplified in.Figure 1 as heavy rolls of sheet material, the operator is always carried above-and out of the reach of the load and the piled material, should the rolls slip and tumble to the floor. I-Ieretofore g5 the handling of such rolls has proved extremely haxardous. My apparatus removes this hazard.o

More particularly, my apparatus comprises v a truck 2 provided with flanged wheels 3v ce adapted to roll on the rail 4;,'supported by suitable framework '6. Asimilar truck and supporting rail are disposed apart from and arallell -with the truck 2 and its rail 4; and

earns 7l span the intervening space and tie the trucks ether, to form a longitudinally movable carriage. Motion is imparted to the carriage by the reversible motor 8 thru its pin- 1 ion 9, the chain 11 and the sprocket 12 ixed to one of the wheels 3. Rails 13 mounted on; the beams 7 rovide a trackwayjor the transversely mova le-carriage 14, carried on the anged rollers 16 which are fixed for rotation with the shaft 17, suitably journaled in bearings on the carriage, and gearing'lS connects the shaft 17 with a reversible motor 19, which furnishes motive power 'for the`carriage-14.

-Secured to the underside of the transversely movable carriage, and forming -a partthereof, is the hoisting mechanism comprising the drum 21 upon which the cable 22 is wound, and the motor 23v operatively connected to the drum by the gears 24. The cable 22 passes from the drum thru a sheav 25 and thence' to the carriage adjacent the rum where the vend is secured by an suitable means. The

sheave is provided with a .pivotally mounted eye 26 in which is supported the frame 27 of the grappling means. An operators sta,- tion is provided adjacent the grappling means comprising the arm 28 carrying the seat 29. Remote control of all `motors is provided by directing the leads therefromy thru the cable 31 to the push button switch box 32 -within .eas reach of the operator.- l

Means or picking up the heavy rolls 33, are provided on the frame 27. Formed on each side of the frame is a sleeve 34, in which a bar 35 is slidably disposed. Keys 36 pre- 100 so that rotation of the gears 41 in the same4 direction rocks the two grappling arms on their pivot pins tou-'ard and from each other. Shaft 43 suitably journaled in the bearing 44, fixed to the slotted ends of the arms by the pivot pins 39, carry gears 46 in mesh with the cam collar gears 41. Each of these shafts isA slidable in and rotatably engaged with a sleeve 47 journaled in suitable bearings 48 on the frame 27. l

lThe keys4 49 lix the shafts 43 for rotation With thesleeve; and collars 50 prevent lateral movement of the sleeve, While collars 51 cooperate With the hubs of the gears 46 in preventing lateral displacement of the shafts in the bearings 44. Thus the cam gears 41 are connected for synchronous rotation, thru the extensible shafts 43. Means for rotating the shafts-are provided inthe lever 52, having in its hub a key 53 slidable in the keyWay 54 of the sleeve 47. The lever may thus be positioned to the `right or left of the operator at will. Rotation of the vsleeve and connected shafts by thelever 52, rotates the cam gears 41, and causes a rocking movement of the grappling arms 38 from retracted to extended positions vice versa, as indicated by the full and dash-and-dot 'lines in Figures 2.

Lateral adjustment for the grappling arms beyond that afforded by the cam collars is provided in the spindle 56,- having right and left hand vthreads at the ends thereof, vand which engage mating threads in the ends of the slide bars 34. A shaft 57 journaled in the bearing 58, which is fixed to the frame 27 has a hand wheel 59 at its outer end, andl at its inner end a miter gear 60, meshing with a Similar gear 61 fixed for rotation with the spindle 56. Lateral movement of the slide bars 34 is accomplished by rotating the hand- Wheel 59 which rotates the spindle 56 and moves the slide bars along the threads.

Since in handling objects beyond the maximum capacity of the grappling frame it is desirable to change to a larger frame, means vare provided :for its quick attachment to and release from the eye 26 of the sheave. The upper end of the frame 27 is provided. with a pair of spaced lugs 63, between whlch the eye `26 of the lsheave is adapted to lie. A pin 64 having annular grooves 66 therein passes thru the lugs and eye; and is demountably retained in the lugs by a pair of spring pressed bolts 67 the inner ends of which engage in the grooves. v

Thus a single operator safely seated on the arm 28 of the grappling frame, and with all the controls of the apparatus within handy reach, is enabled to Work over a large area,

With speed and accuracy, piling and rearranging or delivering rolls of paper or felt weighing many hundreds of pounds.

I claim:

1. In an apparatus for handlingheavy objects, a pendantly supported frame, slide hars arranged on said frame, means for extending and retracting the slide bars, opposed hooks pivotally mounted on the slide bars, and means for rocking the hooks on their pivots.

2. In an apparatus for handling heavy objects, a pendantly supported frame, oppositely extending slide bars arranged on said frame, a threaded spindle operatively engaged with the slide bars to extend or retract them, means for rotating said spindle, opposed hooks pivoted on the slide bars, and means for rocking the hooks on their pivots.

3. In an apparatus for handling heavy objects, a pendantly supported fran'lc, oppositely extending slide bars arranged on said frame, a threaded spindle operatively engaged With the slide bars to extend or retract them, means for rotating said spindle, opposed hooks pivoted onztheslide bars, a cam collar on each slide bar for` controlling the pivotal movement of the hooks thereon, and means for simultaneously moving the 'cams'.

4. In an apparatus for handling'heavy objects, a pendantly supported frame, oppositely extending slide bars mounted on the frame, means for extending and retracting the slide bars, opposed hooks pivotally mounted on the slide bars, an extensible shaft journaled on the :frame adjacent the slide bars, means for rotating. said shaft, gears mounted ontsaid shaft, vand geared cams meshing With said mountings. y

5. In an apparatus for handling heavy obof hooks pivotally and slidably mounted on said frame, an operators seat medially mounted on said frame, and controls for said hooks adjacent said seat. 6. In an apparatus for handling heavy objects', a pendantly 'supported frame, a pair of hooks pivotally and -slidably` mounted on said frame, an operators seat medially mounted gears for rocking the hooks on their `jects, a pendantly supported frame, a pair on said frame, and manual controls for said hooks adjacent said seat.

In testimony whereof, `I. have hereunto set my hand.
